Computer simulation model concept of an automated sorting system
Dvořák, Patrik ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
In response to the growing demand for fast sorting of items, this bachelor thesis focuses on automated sorting systems. It describes the whole system in detail, from the basic principle, to the partitioning, the technologies and sensors used, to the advantages and diverse applications. It includes current trends for small volume shipments in this area. The thesis presents the concept and layout used to create the simulation model in Tecnomatix Plant Simulation software from Siemens. A matrix of experiments was created for the simulation model. Subsequently, simulation experiments were performed to find an optimization solution. Finally, verification and validation was performed where the simulation model was compared with the analytical calculation result.

Analysis of selected effects on water management solution storage function of reservoir system
Čechová, Martina ; Daniel,, Marton (referee) ; Menšík, Pavel (advisor)
The bachelor thesis deals with the influence of the effect of water loss by evaporation in the water management solution storage function of reservoir system. To determine the size of the effect of water loss by evaporation is used simulation model. The simulation model is created with SOMVS. Determining the size of water losses from reservoirs is made simplified method. Loss of water by evaporation is solved for selected level hydrologic reliability of evaporation. To find the optimal size of the storage volume of the proposed reservoir are used all optimization methods included in the SOMVS, that is the grid method, Monte Carlo method, the modified gradient method and differential evolution.
Problematic of Fast Automatic Tool Change by Working Machinery
Pavlík, Jan ; Marek, Jiří (referee) ; Velíšek,, Karol (referee) ; Demeč, Peter (referee) ; Kolíbal, Zdeněk (advisor)
This dissertation thesis is focused on the problem of the Automatic Tool Change for milling centers, which is recently shown as a very current topic. The content of this work is to conduct a comprehensive research of various types of ATC depending on the type of machine, as well as research of the current tool interface relating closely with these problems. There was made a comprehensive analysis on the basis of data obtained by comprehensive research, from which both the main factors affecting this topic and the area dealed and developed by this work resulted. The most problematic area of machinery used nowdays for the Atomatic Tool Change was detected as manipulator provided the exchange between spindle and tool storage. Kinematic structure and design of individual elements affects very significantly the dynamics of the whole process of exchange of tools. Therefore, the work is focused on problematic of the manipulator. The main results of this thesis are constructional design of several types of manipulators, which were partly realized within the project 1.2.4 of Brno department of RCMT in the form of the testing stands. There was developed simulation models for selected types of manipulators which were verificated by measuring on the real stand. On the basis of abovementioned problem there was identified another key issue related not only to the exchange process but also with complex problem of service life of spindle. It is a grab force in the process of picking tools. The work outlines the possibilities for further research of these forces on the service file of spindle (especially on service life of bering groups of spindle).
Modelling of the Gear Pump Manufacturing
Horák, Michal ; Rožňák, Ing Martin (referee) ; Videcká, Zdeňka (advisor)
The diploma thesis deals with the analysis and optimization of production lines of the gear pump components. Specifically, it is pre-production, ie a production line for machining gears and production line for machining of bodies. These two components are then assembled on the assembly line. The creation of a simulation model in the Tecnomatix Plant Simulation program, which corresponds to the real state of production lines, is used for optimization. The simulation model is then used to perform the proposed experiments in order to optimize production lines and select the ideal solution with respect to the selected objectives.
Application of the prediction model on the control of hydropower function of selected multi-reservoir system
Šejnoha, Michal ; Marton, Daniel (referee) ; Menšík, Pavel (advisor)
The diploma sthesis is focused on verifying the influence of the length of the prediction period and the accuracy of the predicted mean monthly inflows of water sources in the management of hydropower function selected water management system. To determine the predicted inflows into the reservoir system is applied zonal prediction model. When the solution is used a simulation model that is hand-built in Microsoft Excel and optimization model, which is automatically built into the program SOMVS and is applying the principles of adaptive control.
Simulation and optimization model of reservoir system in Svitava river basin
Šejnoha, Michal ; Marton, Daniel (referee) ; Menšík, Pavel (advisor)
The bachelor´s thesis is focused on the construction of a simulation and optimization model selected water management system. Both models are created with program SOMVS. The simulation model is based on the choice improved outflow from reservoir searching of boundaries Assurance classes. The simulation model simulates the flow of water through the system. Not finding the optimal solution using optimization methods. In the optimization model is used optimization method of differential evolution. The optimization model seeks maximized value of the objective function for water withdrawal from selected profile.
